On the other hand, the mobile communication terminals MS1 to MSm are constructed as follows. FIG. 3 is a block diagram showing the functional configuration.

That is, the radio signal transmitted from the connected base station is received by the antenna 1 and then input to the receiving circuit (RX) 3 via the antenna duplexer (DUP) 2. The receiving circuit 3 mixes the received radio signal with the local oscillation signal output from the frequency synthesizer (SYN) 4 and frequency-converts (down-converts) it into an intermediate frequency signal. Then, the intermediate frequency signal is orthogonally demodulated and a reception baseband signal is output. The frequency of the local oscillation signal generated from the frequency synthesizer 4 is specified by the control signal SYC from the control unit 12.

The received baseband signal is input to the CDMA signal processing section 6. The CDMA signal processing unit 6 is RAK
E is equipped with a receiver. In the RAKE receiver, the plurality of paths included in the received baseband signal are despread by the spreading code. Then, the signals of the respective despread-processed paths are phase-matched and then combined. As a result, received packet data in a predetermined transmission format can be obtained. Then, the received packet data is input to the compression / expansion processing unit (hereinafter referred to as compander) 7.

The compander 7 demultiplexes the received packet data output from the CDMA signal processing unit 6 into media by a demultiplexing unit. Then, a decoding process is performed for each of the separated media data. For example, if the received packet data includes audio data, this audio data is decoded by the speech codec.
If the received packet data includes video data, this video data is decoded by the video codec. The digital audio signal obtained by this decoding process is input to the PCM code processing unit (hereinafter referred to as PCM codec) 8, and the digital video signal is input to the control unit 12. Furthermore, when the received packet data includes text data such as mail, this text data is input to the control unit 12.

The PCM codec 8 PCM-decodes the digital audio signal output from the compander 7 and outputs an analog audio signal. This analog audio signal is amplified by the reception amplifier 9 and then output from the speaker 10.

The control unit 12 displays the digital video signal output from the compander 7 on the LCD (Liquid Crystal Devise) of the display unit 15 using the video RAM. In addition, text data such as e-mail is stored in the storage unit 1.
6 is stored and displayed on the LCD of the display unit 15. If, for example, the answering machine mode is set in the input unit 14, the audio data and the video data before being decoded by the compander 7 are fetched and stored in the answering machine recording area in the storage unit 16. Let

On the other hand, the voice signal of the speaker input to the microphone 11 is amplified to a proper level by the transmission amplifier 13, and then PCM coded by the PCM codec 8 to become a digital audio signal. It is input to the compander 7. A video signal picked up by a camera (not shown) is digitized by the controller 12 and input to the compander 7. The text data such as mail created by the control unit 12 is also input from the control unit 12 to the compander 7.

The compander 7 detects the energy amount of the input voice from the digital audio signal output from the PCM codec 8 and determines the transmission data rate based on the detection result. Then, the digital audio signal is encoded into a signal having a format corresponding to the transmission data rate, thereby generating audio data. Also, the digital video signal output from the control unit 12 is encoded to generate video data. Then, these audio data and image data are packetized by a demultiplexing unit according to a predetermined transmission format, and this transmission packet data is output to the CDMA signal processing unit 6. Even when text data such as a mail is output from the control unit 12, the text data is multiplexed with the transmission packet data.

The CDMA signal processing unit 6 performs spread spectrum processing on the transmission packet data output from the compander 7 using the spreading code assigned to the transmission channel. Then, the output signal is transmitted to the transmission circuit (T
X) 5 is output. The transmission circuit 5 modulates the spread spectrum signal using a digital modulation method such as a QPSK method. Then, the transmission signal generated by this modulation is combined with the local oscillation signal generated from the frequency synthesizer 4 and frequency-converted into a radio signal.
Then, the radio signal is subjected to high frequency amplification so as to have the transmission power level instructed by the control unit 12. This amplified radio signal is transmitted via the antenna duplexer 2 to the antenna 1
And is transmitted from the antenna 1 to the connected base station.

In addition to the dial keys, the input section 14 is provided with function keys such as a transmission key, an end key, a power supply key, a volume control key and a mode designation key. In addition, the display unit 15
Is provided with an LCD and an LED.

Performs call processing to the emergency management center.

The positioning control function 12b executes a positioning sequence with the position detection device PD when a positioning instruction is received from the position detection device PD in response to the call by the emergency call control function 12a. In this positioning sequence, for example, the latitude / longitude of the terminal itself is calculated based on the GPS signal received by the GPS receiver 19, and the calculation result is notified to the position detection device PD. Position detector PD

Is displayed and emergency notification information is created. Then, based on the email address of the emergency contact stored in advance in the emergency contact database 16a, the emergency notification information is transmitted to the emergency contact by electronic mail.

Therefore, when the mobile communication terminal MS1 makes an emergency call, the emergency notification information indicating the location of the mobile communication terminal is created based on the position information notified from the position detection device PD of the mobile communication network MNW. Then, this emergency notification information is automatically transmitted to an emergency contact registered in advance by e-mail. For this reason, the user of the mobile communication terminal does not need to perform an operation of contacting an emergency contact such as a family member or an office separately from the emergency call operation, and thus the operation load on the user in an emergency is significantly reduced. In addition, an emergency contact such as a family member or an office can quickly know an emergency situation that has occurred in a mobile communication terminal user together with its current position, and thereby, appropriate response measures such as rescue can be promptly executed. .
